RIPE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 257,983, dated May 16, 1882.

Application December 13, 1881.

To all whom it may concern:

Be it known that I, LEVI T. SooFtELn, of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvementsin Pipe-Couplings; and I do hereby declare the following to be a full,

' clear, and exact description of the invention,

such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to pipecouplings, and is morepartieularly adapted to couple pipes that run at an angle to each other; and it consists in the peculiar construction of the same, aswillbehereinafterfullysetiorth and claimed.

In the drawings, Figure 1 is a view showin g my coupling as adapted and applied to a steam-radiator. Fig. 2 is an enlarged view of my hollow plug as preferably constructed. Fig. 3 is a longitudinal vertical sectional "iew of the same. Fig. 4 is a sectional View of the interior of the socket or head through which the plug passes. Fig. 5 is a modification showing another manner of constructing my couplin g is a pipe the upper end of which is provided with a head or socket, B, the orifice of this socket being at an angle to the orifice of the pipe A O is a hollow plug, which is closed at one end, a, and open at the other, I), and adapted to fit in the head or socket B in such a manner that its end b extends somewhat beyond the said head or socket. The interior of the plug G is made tocommunicate with the interior of the pipe A, by providing it with an opening, 0, (see Figs. 2 and 3,) and providing the interior of the head or socket B with a groove, d, which extends around the inner circumference of said socket directly over the pipeA, and thus secures communication between the pipe A and plug 0, no matter in (N0 model.)

what position the plug 0 may be turned, or

the communication between the pipe A and plug 0 may be secured in many other ways, another manner being shown in Fig. 5, which will be readily understood without any explanation.

To the open end I) of the plug 0, is connected the pipe D, to which the pipe Ais to be attached, and thus communioatioliis established between them. The contents of the pipe A flow from said pipe into the interior of the plug 0, through the opening 0, and from thence through the open end 0, into the pipe D.

Instead of connecting the end b of the plug C to the pipe D, it may be connected directly to any vessel, tank, boiler, or like supply or receiver.

WhatI claim is- A coupling for securing communication betweena pipe and avessel, or between two pipes, consisting of a hollow plug open at one end and closed at the other with a hexagonal cap, so that it can be turned with a wrench, the outer surface of .said plug beinga male thread of tapering form and provided with a hole on its side, so that when screwed tight in a valve, vessel, or socket forming a part of the coupling, the opening will be the only communication between the pipes or pipe and vessel through the plug, said socket being provided with a grooved chamber encirclingthe plug at the opening, substantially as and for the purpose set forth.

' In testimony whereof, I have signed my name to this specification in the presence of two sub scribing witnesses.
